300-430 Question 70
Single answerA network engineer is tasked with implementing multicast on a Cisco wireless network to support a video streaming application. The application requires efficient delivery of multicast traffic to all wireless clients while minimizing unnecessary traffic on the wireless network. Which component should the engineer implement to optimize multicast delivery in this scenario?
- A
Multicast-to-Unicast Conversion
- B
Multicast Listener Discovery (MLD) Proxy
- C
Protocol Independent Multicast (PIM) Sparse Mode
- D
Internet Group Management Protocol (IGMP) Snooping
Show answer and explanation
Correct answer: A
Explanation
In wireless networks, multicast traffic is typically delivered as broadcast frames, which can lead to inefficiencies. To address this, Cisco wireless controllers can use Multicast-to-Unicast Conversion, delivering multicast streams as unicast frames to each client. This approach ensures efficient delivery while avoiding broadcast overhead, making it the optimal solution for this scenario.
- A. Correct.
Multicast-to-Unicast Conversion is the correct solution for optimizing multicast traffic in wireless environments, as it converts multicast traffic to unicast for each client, reducing unnecessary traffic on the wireless network.
- B. Incorrect.
Multicast Listener Discovery (MLD) Proxy is used in IPv6 multicast environments, but it is not relevant to optimizing multicast delivery in a Cisco wireless network.
- C. Incorrect.
Protocol Independent Multicast (PIM) Sparse Mode is used for multicast routing in wired networks, but it does not directly address multicast delivery optimization in wireless networks.
- D. Incorrect.
Internet Group Management Protocol (IGMP) Snooping helps manage multicast group memberships on switches but does not optimize multicast delivery in wireless networks.
